  1. I just finished this one and everything works as it should although with all the subs it sounds different than the original. I compared it to my original pw2 and it gains up quite differently.
    For the three jfets I used a mix of 201s and a 5457. For the IC I used a 5532, and I didnt have the smaller zener so used a 3,5. To me, it looks like the layout is good just a lot of changes which makes it sound different, although still awesome and completely usable.
    This circuit is such a sleeper, especially with the gain pot turned all the way down it gives this super woody Overdrive with a tad of splat.

  2. One useful modification.. I found that the bass pot did almost nothing with that horizontal 68nf connected to base of q6. Lowering the value makes it more usable in my case, I chose a 2n2.

    PLEASE make it fit into a 1590B - battery is not required...

  5. The layout is updated with the correct resistor and zener values.
